Abstract

The present invention provides an apparatus and method for moving playing cards from a first group of cards into plural hands of cards, wherein each of the hands contains a random arrangement of cards. The apparatus comprises a card receiver for receiving the first group of cards, a single stack of card-receiving compartments generally adjacent to the card receiver, the stack generally vertically movable, an elevator for moving the stack, a card-moving mechanism between the card receiver and the stack, and a microprocessor that controls the card-moving mechanism and the elevator so that an individual card is moved into an identified compartment. The number of compartments receiving cards and the number of cards moved to each compartment may be selected. An apparatus for feeding cards, comprising a surface for supporting a stack of cards, a feed roller with a frictional outer surface, a drive mechanism for causing rotation of the feed roller, a pair of speed-up rollers to advance the cards out of the feed roller, and a clutch mechanism for disengaging the feed roller from the drive mechanism as the card comes into contact with the speed up rollers.

Claims

1. An apparatus for handling cards comprising:

a card loading area for receiving a group of cards to be arranged within the apparatus into a plurality of randomized sets of cards and each randomized set of cards is delivered to a same single tray to form sets of cards to be used in a card game;

a shuffling chamber having a plurality of card-receiving compartments, wherein each compartment is able to receive more than one card within an opening of the card-receiving compartment, wherein the same single tray is separate from an area in the apparatus for the forming the plurality of randomized sets of cards,

a card moving system comprising two sequential single card moving components positioned for moving at least one card at a time from the card loading area into a card-receiving compartment,

the two sequential card single card moving components comprising a first single card moving component that moves at least a single card from the card loading area towards a second card moving component and the second card moving component receiving the individual card from the first card moving component, and

a microprocessor for controlling card movement;

wherein the first single card moving component reduces moving forces against the single card when the second card moving component applies moving forces against the single card.

2. The apparatus of claim 1 wherein the card moving mechanism moves only one card at a time into a card-receiving compartment.

3. The apparatus of claim 2 wherein each card-receiving compartment receives cards comprising a set of cards selected from the group consisting of players'"'"' hands, dealer'"'"'s hands, discards, and excess cards.

4. The method of claim 3 wherein individual sets of randomly mixed playing cards are delivered to the single delivery tray and the single delivery tray in the apparatus can be accessed so that two edges of cards in the delivery tray can be contacted by a hand of a dealer.

5. The method of claim 4 wherein after at least one individual set of randomly mixed playing cards is manually removed from the delivery tray, another individual set of randomly mixed playing cards is delivered from the apparatus to the delivery tray.

6. The method of claim 3 wherein at least one, but less than all individual sets of randomly mixed playing cards are a subset of cards that is delivered to a dealer as a hand.

7. The apparatus of claim 1 wherein the each individual randomized set of cards is delivered to the tray, as a single delivery step, as a group of cards.

8. The method of claim 7 wherein each set of randomly mixed playing cards delivered from the apparatus to the tray is then delivered to a position on a gaming table that is distinct from a position where another set of randomly mixed playing cards is delivered from that same tray in a single card game.

9. The apparatus of claim 1 wherein a separator is located between each adjacent card-receiving compartment, and there is an edge of the separator that a card moved into card-receiving compartments contacts before that card is fully inserted into a card-receiving compartment.

10. The method of claim 9 wherein the total number of cards in sets of randomly mixed playing cards are hands delivered from the apparatus, and the hands comprise a total number of cards that are less than the total of the at least one deck of cards.

11. The apparatus of claim 1 wherein the shuffling chamber comprises a configuration selected from the group:

a carousel, a vertical mixing stack and a fan shape.

12. The apparatus of claim 1, wherein each card-receiving compartment is of the same size.

13. The apparatus of claim 1, wherein not all of the card-receiving compartments are of the same size.

14. A method for delivering hands of randomly mixed cards from an apparatus comprising:

providing at least one deck of playing cards;

providing a shuffling chamber in the apparatus;

forming at least one set of playing cards within the shuffling chamber from the at least one deck of playing cards;

delivering to a single delivery tray from the at least one set of cards within the shuffling chamber a first individual set of randomly mixed playing cards for use in a game, wherein the single delivery tray is separate from the shuffling chamber for the forming of the at least one set of playing cards;

delivering to a player or dealer the first individual set of randomly mixed playing cards from the single delivery tray of the apparatus, with all playing cards in the first individual set delivered at the same time, and then forming a second individual set of randomly mixed playing cards in the shuffling chamber, an delivering the second individual set of randomly mixed playing cards into the same single delivery tray in the play of a single round of cards.

15. The method of claim 14 wherein all sets of randomly mixed playing cards are delivered to a storage area within the apparatus without removal of previous sets of randomly mixed playing cards from the storage area.

16. A method in an apparatus for delivering hands of randomly mixed cards comprising:

providing at least one deck of playing cards in the apparatus;

providing a shuffling chamber in the apparatus;

forming a first group of randomly mixed playing cards in the shuffling chamber from the at least one deck of playing cards;

delivering to a single delivery tray, the first group of randomly mixed playing cards with all cards in the group present in the single delivery tray at the same time;

removing the group of randomized cards from the single delivery tray; and

forming a second individual group of randomly mixed playing cards in the shuffling chamber, and delivering the second group of randomly mixed playing cards to the same single delivery tray after the first group of randomized cards are removed from the same single delivery tray and put into play to form a hand for another player or dealer at the table in a single card game.

17. The method of claim 16 wherein each formed group of cards is a hand of cards.

18. The method of claim 16 wherein after at least one individual hand is manually removed from the delivery tray, another individual hand is automatically delivered from the apparatus to the delivery tray.

19. The method of claim 18 wherein the total number of cards in hands delivered from the apparatus comprise a total number of cards that is less than the total of the at least one deck of cards.

20. The method of claim 16 wherein at least one, but less than all individual hands is a subset of cards that is delivered to a dealer as a hand and each hand delivered from the apparatus to the tray is then delivered to a position on a gaming table that is distinct from a position where another hand is delivered.

21. A method in an apparatus for delivering hands of randomly mixed cards comprising:

providing at least one deck of playing cards in the apparatus;

providing a shuffling chamber in the apparatus;

randomly forming a group of playing cards in the shuffling chamber from the at least one deck of playing cards;
